ITS THE PLANT WORLD. j 



plant found on Pinus contorta at the highest elevations, as on 

 Mount Constitution and Turtle Back Mountain. Before leav- 

 ing the flowering plants, we must mention Plantago maritima 

 and three members of the genus Rubus. viz., the thimble borrv, 

 Ruhus parvijiorus, the salmon berrj, Rubus spectabilis, and the 

 dew berry, Rubus macropetalus. 



The common brake, Pteris aquilliKi. is very common and 

 grows to enormous size. We repeatedly measured specimens 

 more than twelve feet high. Mosses are also unusually abundant 

 and luxuriant. On logs and on the groimd in woods several 

 species of llylocomium and Hy pint in are very common. ]>(ir- 

 bula inembranifolia is abundant on the ground in places, while 

 Polyfrirlium piUfenun was often seen on the same substratum. 

 Mnlnin inenziesii and two or tliree species of Necl'era are very 

 common on the trees. The leafy hepatic, Porella navlcuJans. is 

 common on trees, and fruited specimens may be found for st\uly 

 in oreat abundance. 



Of the marine alga\ the giant kelp, Xcrcucytis lueth'caiKi . 

 with its long stem, bladder or float and several laminse, is the 

 most noticeable. This plant adjusts itself in length to the depth 

 of the water in which it grows, and specimens were measured 

 more than seventy feet long. Clinging to this are Ulva lacfuca. 

 Enteroiiiurpha intestinalis, Enteromorphu liiiza, and other alga-, 

 while the beautiful Porphyra naiadum, like dentist rubber, clings 

 in similar fashion to eel grass, Zostera marina. Even more in- 

 teresting than anv of these are two coenocytic algae, C odium nni- 

 cronafuin and Bryopsis plumosa. The former is found on rocks 

 at loAV tides, and except for its dichotomous branching, looks not 

 unlike certain fresh water sponges. The delicate little Bryopsis 

 is eaa'erlv sought bv teachers for class use, but is bv no means 

 easily found, though doubtless common enough. Besides these, 

 Fucus evanescens, HaJosaccion glandiforme, Soranthea ulvoides, 

 Calpomenia sinuosa, Costaria turneri. HedophyUum sessile, Cor- 

 allliia officinalis, Amphiroa tubercidosa. RJwdomela larix. Des- 

 marestia aculeata, Cystophyllum geminatum, Cigartina mainil-
